Tinea Versicolor Treatment Tips

Tinea Versicolor, also known as pityriasis versicolor. Tinea versicolor is a fungus infection that commonly affects the skin of young people, especially the chest, back, and upper arms and legs. It is found mostly in young people. The fungus interferes with the normal tanning of the skin. This results in small areas that are lighter than surrounding skin. Any person infected with this will have discolored patches on his skin. These patches can be light or reddish-brown in colour. It is neither a permanent nor a serious infection. The most common symptoms of tinea versicolor are light brown or white patches on the skin. These patches are most noticeable during summer season. Rashes on the trunk are one of the symptoms. Generally rashes of tinea versicolor do not appear on the face.Itch on the patches, which become more intense with sweat or overheating. Tinea versicolor occurs more frequently in areas with higher temperatures and higher relative humidities. The national prevalence of this condition is 2-8% of the population. It is estimated that 2 to 8% of the population of the United States has it. The infection is easily treated with skin creams, shampoos, or solutions. Topical antifungal medications - containing either 2.5% selenium sulfide or 2% ketoconazole (Nizoral ointment and shampoo) applied to dry skin and washed off after 10 minutes. Apply antidandruff shampoo that contains selenium sulfide on the patches. Take bath daily, this will remove dead cells and fungus from your skin. Selenium sulfide 2.5% lotion regimen for 1 week. Some home remedies also reduce patches. Garlic is a very good antifungal agent. Try chewing one or two cloves daily. Include raw fruits, raw vegetables and whole grains in your diet.

Jock Itch Information

Jock itch, also known as tinea cruris, is a fungal infection of the skin in the groin and upper thighs. The fungus that most commonly causes jock itch is called Trichophyton rubrum. Trichophyton rubrum also causes fungal infections of the toes and body. Lesions caused by jock itch can extend from the crease between the inner thigh and pelvis, over the adjacent upper inner thigh, and into the anal area.Jock itch differs from genital herpes in that it usually doesn’t develop on the scrotum or penis. It tends to spread in the inner thigh area instead. However, a jock itch rash may also affect the genitals and areas around the anus, rectum, or vagina. The skin may crack, scale and be painful, but it usually won’t present open lesions like it would with genital herpes. Genital herpes doesn’t cause long-term infections. Healthy skin returns after 3 weeks, although slight change in skin color may result.CausesThe fungus that most commonly causes jock itch is called Trichophyton rubrum. It also causes fungal infections of the toes and body. Under the microscope, this fungus looks like translucent, branching, rod-shaped filaments or hyphae. The width of the hyphae is uniform throughout which helps distinguish it from hair, which tapers at the end. Some hyphae appear to have bubbles within their walls, also distinguishing them from hair. Under most conditions these fungi inhabit only the dead skin cells of the epidermis.Jock itch is caused by the same fungus that causes ringworm (tinea cruris). Jock itch is much more common in men than in women and develops most frequently in warm weather. The infection begins in the skinfolds of the genital area and can spread to the buttocks, upper inner thighs, armpits and underneath the breasts. Usually the scrotum is not involved (unlike in yeast infection). Anyone can get jock itch. Jock itch named because it is usually athletes who get it, but it can affect anyone who tend to be overweight or sweat a lot.SymptomsThere are several different jock itch symptoms that will let you know if you have it. Do you notice a circular, raised, red rash around your groin? Have you been experiencing a lot of itching? Does it seem like the more you scratch, the more you itch? Have you had any flaking or peeling of your skin in the groin area? All of these are classic symptoms.A circular, red, raised rash with elevated edges. Itching and redness in your groin, including your genitals, inner thighs, buttocks and anal area. Flaking, peeling or cracking skin in your groin. Abnormally dark or light skin. You may have other fungal skin rashes such as athlete’s foot or ringworm on other body parts. TreatmentSevere infections, frequently recurring infections, or infections lasting longer than two weeks may require further treatment by your doctor. Stronger prescription medications, such as those containing ketoconazole or terbinafine, or oral antifungals may be needed. Antibiotics may be needed to treat bacterial infections that occur in addition to the fungus (for example, from scratching the area).Side effects from oral medications include gastrointestinal upset, rash and abnormal liver function. Taking other medications, such as antacid therapies for ulcer disease or gastroesophageal reflux disease (GERD), may interfere with the absorption of these drugs. Oral medications for fungal infection may alter the effectiveness of warfarin, an anticoagulant drug that decreases the clotting ability of your blood.

Clinical Presentation-Skin Disorders

Tinea capitis, or “ringworm” of the scalp, presents as one or more sharply marginated plaques of partial alopecia. Inflammation and scale are present, but often these two changes are quite minimal. The recognition of broken hairs (stubble and black dots at the follicular orifices) is the best clue to correct diagnosis. Nearly all cases occur in children, but the diagnosis should be considered in any adult presenting with evidence of localized alopecia . Kerion formation is a complication that occurs in about 10% of cases. This represents a sensitization phenomenon whereby the fungi induce a remarkably brisk inflammatory reaction with resulting pustulation, crusting, and edema formation. Wood’s lamp examination does not reveal fluorescence in the most common forms of tinea capitis or in kerion formation. Unfortunately, KOH preparations are difficult for the inexperienced to interpret. For this reason, any suspected diagnosis requires the plucking of infected hairs for fungal culture. Course and PrognosisTinea capitis and zoophilic tinea corporis usually resolve spontaneously after 6 to 12 months of activity. Tinea pedis, tinea cruris, and anthropophilic tinea corporis continue indefinitely. There are, however, periods of relative quiescence and exacerbation. All of these fungal diseases respond well to treatment, but with the exception of tinea capitis and zoophilic tinea corporis infections, recurrence following treatment is rather likely. PathogenesisTinea pedis, tinea cruris, and anthropophilic tinea corporis are most commonly caused by Trichophyton rulnum. Trichophyton interdigitate and Epidermophhyton floccoswn infections are also seen. Generally, one cannot predict the causative organism on the basis of clinical appearance. Zoophilic tinea corporis can be caused by Microsporum canis, Trichophyton mentagrophytes, and Trichophyton verrucosum. Tinea capitis is caused by Trichophyton tonsurans in 90% of cases. The likelihood of inoculation with any of these fungi is enhanced if cuts and scratches are present on the skin. Clinical evidence of infection following inoculation is enhanced by the presence of warmth and moisture, such as occurs in the groin and under footwear. Depression of cell-mediated immune responsiveness, as in atopic patients, is a major predisposing factor for the development of T. rubrum infection. TherapyTinea cruris and those cases of tinea pedis that involve only the web spaces can be treated with any of the topical antifungal agents. Other forms of tinea pedis usually require the use of griseofulvin. Mild cases of tinea corporis also respond well to topical agents. Extensive disease and those cases with a component of follicular involvement are best treated with griseofulvin. Tinea capitis requires the use of griseofulvin. Orally administered ketoconazole therapy is rarely appropriate for either tinea corporis or capitis. Kerion on nation, if present, can be treated with intralesional steroid injections or with a short burst of systemically administered steroids.

Hair Loss In Children: Why My Child?

Children often take hair loss better than adults, up until the age of ten. Less of their identity is tied into their appearance, and so the loss of hair is not as shocking for them. There are several reasons that a child may lose their hair which are not life threatening.Common Reasons for Childhood Hair LossA reason that many children begin losing their hair is Tinea Captis, also known as ringworm of the scalp. This is a fungal infection which affects both the hair follicles and individual strands. If not treated with medicine immediately, it can be contagious.Another reason for childhood hair loss is Alopecia Areata, which can cause baldspots on the head and other areas of body hair. It is theorized to occur when the immune system begins attacking follicles. With treatment started immediately, some body hair may be saved.Another cause of childhood hair loss is called Trichotillomania. It is a self-inflicted condition which is considered on the obsessive compulsive spectrum. In it, a child feels the need to obsessively pluck hair from their head.This condition is usually treated with some kind of behavioral therapy, often including relaxation techniques. Because the hair follicle is not usually damaged, hair should grow back when the plucking of it is ended.Other conditions which can cause hair to stop growing include individual trauma, and traction alopecia. In this disease, the hair is pulled at or rubbed constantly. The resulting trauma to the hair shaft can cause hair to stop growing. Severe hair styles may also cause this reaction.A body’s response to trauma can also lead to hair loss. After a traumatic event, some people’s bodies withdraw nutrients from the hair, causing it to fall out. Hair loss does not need to traumatize a child. A parent with the right attitude can help their child through hair loss with support.

Skin Fungus Infections (Symptoms and Treatments)

Defining skin fungal infection• A dermatophyte, a parasitic fungus often becomes the cause of skin infection. The term dermatophyte contains “imperfect fungi” of the species like Epidermophyton, Microsporum and Trichophyton. The most common forms of skin fungus are ringworm, althlet’s foot and cutaneous candidiasis.• Fungi are cluster of organs which often becomes the reason for skin infections. The fungi are known as yeast naturally existed in the human body. Dermatophytes are the occasional organisms positively move according to environmental conditions as they develop in human body and infect top layer of the skin and nails as well as hair.• There are various kinds of fungal skin infections such as ringworm (Tinea Corporis), Athlet’s foot (Tinea Pedis), nail ringworm (Tinea Unguium), jock itch (Tinea Cruris), beard ringworm (Tinea Barbae), scalp ringworm (Tinea capitis) and Candida. The deep fungal infections can stretch into blood and internal parts of the human body due to incursion through deep layers of skin.Symptoms of skin fungal infection • Fungal skin infection is usually occurred due to hives. Ringworm originates red, pink, ring-shaped itchy patches surrounded by an apparent circle.• Jock itch becomes prominent in form of a red ring hives nearby the groin area. It is looked like a small, painful, hurtful and deeply itch wound.• Athlete’s foot originates in form of itch rough rash between the toes. It causes mild frustration, cracking and flaking around the skin surface.• Fungal skin infection is extremely painful and disturbing in its bacterial form. Scalp ringworm is extremely infective in the children.• Nail ringworm impacts on toenails and makes the nail deadly and condensed. Fungal and infected part of the nail is often fallen separately from rest of the nail.• Candida infection is generally occurred in humidity and balmy areas of the human body like skin wrinkles and diaper areas.• Superficial candidal fungal skin infection is occurred in various forms such as red, flat itchiness and prickly edges, etc.• The diminutive scraps and patches are occurred in a rash form known as satellite lesions. These patches can cause acute ache, irritation, agony, and itching.• Skin fungal infection is very contagious, because it not only causes itch patches in one body part but also appears on another body parts. This is called as an “allergic reaction to fungus”.Treatment for Skin Fungal InfectionsDisturbed immune system, antibiotics, corticosteroids, diabetes, dirtiness, and poor medical conditions are the major causes of fungal skin infections. Therefore, the treatment of fungi skin infection is become vital in such state of affairs, discusses as under in some points.• If you want to control upon fungal skin infection you will have to stop corticosteroids, medications and antibiotics.

Ringworm treatment at home

Ringworm is a fungal infection showing as itchy, red, scaly, slightly raised, expanding rings on the trunk, face or groin area. An infection caused by a fungus (not a worm or a parasite). It is extremely contagious and spreads quickly. The most common symptoms are red, itchy, swollen skin in the shape of a ring. The skin in the center of the ring usually appears healthy. The medical term for ringworm is “tinea.” (Tinea gets us back to worms. Tinea is the Latin name for a growing worm.) Doctors add another word to indicate where the fungus is located. Tinea capitis, for instance, refers to scalp ringworm, tinea corporis to fungus of the body, tinea pedis to fungus of the feet, and so on. To catch ringworm, you have to be exposed to it and you have to be susceptible. Some people are much more susceptible than others. Those with eczema or other skin problems get ringworm more easily because the protective barrier of the skin’s outer layer is less intact. Children are more susceptible before puberty. Boys get it more easily than girls. Ringworm of the skin starts as a red, scaly patch or bump. Ringworm tends to be very itchy and uncomfortable. Over time, it may begin to look like a ring or a series of rings with raised, bumpy, scaly borders (the center is often clear). This ring pattern gave ringworm its name, but not every person who’s infected develops the rings. People will sometimes pick up a case of Ringworm from their pet, but just because a pet has Ringworm does not necessarily mean that the people that interact with that pet will develop the problem. A dog or cat can transmit Ringworm to a person without showing any symptoms at all. Ringworm is widespread around the world and in the United States . The fungus that causes scalp Ringworm lives in humans and animals . The fungus that causes Ringworm of the body lives in humans, animals, and soil . The fungi that cause Ringworm of the foot and Ringworm of the nails live only in humans. To avoid ringworm infection, avoid contact with suspicious lesions, wear loose-fitting clothes, avoid sharing clothes, and after showering, dry off completely. Examine all family members for signs of tinea as reinfection may occur. Scalp ringworm (tinea capitis) is primarily caused by Trichophyton. Scalp ringworm is highly contagious and is common among children, especially black children. It may produce a pink scaly rash that may be somewhat itchy, or it may produce a patch of hair loss without a rash. Less commonly it can cause a painful, inflamed, swollen patch on the scalp that sometimes oozes pus. A kerion is caused by an allergic reaction to the fungus. Nails with ringworm may become thick and discoloured, and will sometimes start to crumble. Children are most likely to get ringworm. Ringworm of the scalp can spread from child to child when children share hats, combs, or brushes. Ringworm of the body can be spread on towels, clothing, or sports equipment. Personal hygiene is important in preventing the spread of ringworm. Dogs and cats can be infected with ringworm, too, and they can pass it to people through direct contact. Although unsightly, ringworm usually isn’t serious, except potentially for people with weak immune systems. Treatment usually consists of antifungal medications that you apply to your skin.

Ringworm effects on the skin

Ringworm is a skin infection which, despite its name, is not caused by a worm at all. Ringworm is actually caused by several fungus organisms known as dermatophytes. Ringworm is a fungal infections of the skin resulting in raised red swellings or lines that resemble burrowing worms; includes the diseases known as athlete’s foot, jock itch, and ringworm or the scalp. Ringworm is not caused by a worm. It is caused by a fungus. The kinds of fungi (plural of fungus) that cause ringworm live and spread on the top layer of the skin and on the hair. They grow best in warm, moist areas, such as locker rooms and swimming pools, and in skin folds. Although the world is full of yeasts, molds, and fungi, only a few cause skin problems. These agents are called the dermatophytes, which means “skin fungi.” Skin fungi can only live on the dead layer of keratin protein on top of the skin. They rarely invade deeper into the body and cannot live on mucous membranes, such as those in the mouth or vagina. Body ringworm (tinea corporis) may be caused by Trichophyton, Microsporum, or Epidermophyton. The infection generally produces round patches with pink scaly borders and clear areas in the center. Sometimes the rash is itchy. Body ringworm can develop anywhere on the skin and can spread rapidly to other parts of the body or to other people with whom there is close bodily contact. Ringworm is very mildly contagious. It can be caught from domestic animals (especially dogs and cats) as well as most farm animals. The infection can be caught from the animal directly, or from anything the animal rubs against. Ringworm can also be caught from other humans, both by direct contact and by prolonged contact with flakes of shed skin. Ringworm of the scalp may start as a small sore that resembles a pimple before becoming patchy, flaky, or scaly. It may cause some hair to fall out or break into stubbles. It can also cause the place where the infection is to become swollen, tender, and red. Anyone can get Ringworm . Scalp Ringworm often strikes young children; outbreaks have been recognized in schools, day-care centers, and infant nurseries . School athletes are at risk for scalp Ringworm, Ringworm of the body, and foot Ringworm; there have been outbreaks among high school wrestling teams . Children with young pets are at increased risk for Ringworm of the body. There are several other skin conditions that can mimic the ring-like appearance of ringworm. None of these, however, are serious. They include eczema, contact dermatitis, psoriasis and seborrhea. If treatment for ringworm fails, your doctor may consider these other possibilities. Scalp and beard infections may cause patches of baldness. In scalp infections, the lymph nodes at the back of the neck may become swollen and tender. Inflammation and scaling are usually fairly mild and may look like a patch of dandruff.Diagnosis is usually made based on the appearance of the typical ringworm rash. Cultures, especially scalp cultures for tinea capitis, can be done though. Topical steroids are a usual first treatment most parents use, but this can change the appearance of ringworm, so be sure to mention to your Pediatrician if you have been applying any topical creams to your child’s rash.

Ringworm is a contagious fungus infection that can affect the scalp, the body (particularly the groin), the feet, and the nails. Its name is a bit of confusion as it has nothing to do with worms.

Take a few mustard seeds and powder them. Thereafter, make a paste using water. Apply the paste on the ringworm-affected area and see its wonderful effects.

Ringworm infection occurs in the scalp, the body, the feet, and the nails. Ringworm of the scalp is common among children because of the lack of protective fatty acids in their scalp. The disease spreads on the skin and extends deeper into the hair roots, and also up along the hair. The affected hair becomes dull and breaks off near its root. This leaves bald spots on the scalp.

Raw vegetable juices, especially carrot juice in combination with spinach juice, have proved beneficial in the treatment of ringworm. The formula proportions considered helpful in this combination are 300 ml of carrot juice and 200 ml of spinach juice to make 500 ml or half a litre of juice.

Take turmeric powder and make a paste with water. Apply it over the affected area and allow it to dry. Thereafter, wash off and dry with a towel.

Tea, coffee, condiments, highly flavored dishes, sugar, white flour products, denatured cereals and tinned or bottled foods should be avoided.

Use gentian violet to get rid of ringworm. It is hard to find and is often an ingredient in antifungal applications with other names, so read labels. It is gentle enough to use on children. If you can’t find it in a health food store, look for a feed store that carries supplies for cattle. Gentian violet it liquid and it stains the skin purple so you need to be careful because once it is on the skin it has to fade as the skin exfoliates off.

Treatment of RingwormRingworm, also known as “Tinea,” is an infection of the skin, characterized by a reddish to brownish raised or bumpy patch of skin that may be lighter in the center, giving the appearance of a “ring.” Contrary to its name, ringworm is not caused by a worm but by parasitic fungi (Dermatophytosis). It can exist anywhere on the body.Ringworm of the skin starts as a red, scaly patch or bump. Ringworm tends to be very itchy and uncomfortable. Over time, it may begin to look like a ring or a series of rings with raised, bumpy, scaly borders (the center is often clear). Causes of RingwormRingworm is contagious. It can be passed from one person to the next by direct skin-to-skin contact or by contact with contaminated items such as combs, unwashed clothing, and shower or pool surfaces. You can also catch ringworm from pets that carry the fungus. Cats are common carriers.Many bacteria and fungi live on your body. Some of these are useful to you and your body. Others can multiply rapidly and form infections. Ringworm occurs when a particular type of fungus grows and multiplies anywhere on your skin, scalp, or nails.Most pediatricians do not recommend isolation of afflicted children. Covering the rash with a bandage and a layer of clothing is usually enough to prevent its spread.What are the symptoms of ringwormRingworm of the skin causes itching, redness of the skin, and circular sores. The sores usually have a red edge and a clear center. Rings may form around sores.Skin could become lighter or darker on the sides of the face, the neck, back, and chest. This is most common in teens and young adults.Ringworm of the body shows up as a flat, round patch anywhere on the skin except for the scalp and feet. The groin is a common area of infection (groin Ringworm). As the rash gradually expands, its center clears to produce a ring. More than one patch might appear, and the patches can overlap. The area is sometimes itchy.Diagnosis of Ringworm Diagnosis must rule out other possible causes of the signs and symptoms, which may include eczema, psoriasis and contact dermatitis.A microscopic examination of some lesion scrapings usually will confirm tinea infection. This is called a KOH (potassium hydroxide) preparation. Culture of the affected area, which may take weeks, may help identify the infecting organism.Treatment of RingwormImidazoles (clotrimazole or Lotrimin, miconazole or Micatin, ketoconazole or Nizoral, econazole or Spectazole, oxiconazole or Oxistat, and sulconazole or Exelderm) Side effects from oral medications include gastrointestinal upset, rash and abnormal liver functioning. Taking other medications, such as antacid therapies for ulcer disease or gastroesophageal reflux disease (GERD), may interfere with the absorption of these drugs. Systemic treatment: Some fungus infections do not respond well to external applications. Examples include scalp fungus and fungus of the nails. To penetrate these areas, oral medications are necessary.

Pets like dogs and cats that carry fungus can cause ringworm. The other causes of ringworm are prolonged wetness of the skin and the minor injuries of the skin and nails.Depending on what part of your body is infected with ringworm will determine the length of time it takes to fully cure yourself. Scalp ringworm can take up to ten weeks to cure with a conventional treatment that is prescribed by your doctor. A scalp ringworm cure from your doctor is a shampoo and an oral anti fungal drug. The oral anti fungal is needed because the shampoo in ineffective on its own for the reason it cannot penetrate your scalp to fully cure the infection.Ringworms bleach solution is quite effective for killing fungi but bleach should not be used directly on the skin because: •    It is carcinogenic.•    If absorbed, it can cause lung damage.•    It can burn the skin or cause allergic reactions.Apply the juice of raw turmeric externally to the parts of the skin affected by ringworm. Simultaneously, one teaspoon of turmeric juice mixed with an equal quantity of honey should be taken orally.Mix 5-7 teaspoons of dried Licorice herb per 1 cup of water. Bring it to a boil and simmer for 20 minutes, then let it cool. Apply it directly to the affected area using a cotton ball or clean cloth.Papaya: Rub papaya slices on infected patches or apply paste made from dried papaya seeds.Mustard: Make a paste from mustard seeds.
